What can excessive acidity in soil negatively affect?

Excessive acidity in soil can significantly impact nutrient uptake. Soil acidity affects the availability of essential nutrients to plants. Certain nutrients, such as phosphorus, calcium, and magnesium, become less available in highly acidic conditions, making it difficult for plants to absorb what they need for growth and development. Moreover, highly acidic soils can increase the solubility of toxic elements like aluminum, which can further hinder plant health and nutrient uptake.

While other factors, such as photosynthesis, soil structure, and water retention, may also be influenced by soil acidity, the primary concern is how it directly limits plants' ability to acquire necessary nutrients from the soil, leading to various growth deficiencies and decreased crop yields.
